JAMES T. CARROLL, JR., OF LONG ISLAND CITY, NEW YORK.

BUTTON-MAKING MACHINERY.

Specification of Letters Patent.

Patented July 18, 1911.

Application filed July 24, 1909. Serial No. 509,344.

To @ZZ whom it may concern:

Be it known that I, JAMES T. CARROLL, J r., a citizen of the United States of America, and a. resident of Long Island City, county of Queens, and State of New York, have invented certain new and useful Improvements in Button-Making Machinery, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in button making machinery, and particularly to machines for producing button backs for cloth faced buttons.

The approved form of cloth faced button of the present day has a back comprising a perforated cup shaped metallic portion known as a collet, a washer of fabric which is inserted in the collet, the central portion thereof being caused to protrude thro-ugh the perforation in the collet, and a follower disk of card board or similar material which is pressed into the collet upon the washer and which serves to hold the cloth washer in place. rIhe portion of the cloth washer which projects through the centra-l opening in the collet is employed for the purpose of attaching the button to a garment in use. A crowned facing piece of metal covered with the desired kind and quality of cloth is placed upon the back when the button is being prepared for use, but my present invention relates to the production of the button backs only and not to the crowned facing pieces or shells.

In carrying o-ut my invention I preferably employ previously manufactured collets for the reception of which I conveniently provide a reservoir or hopper. Fabric is fed into the machine in strips and disks or washers o-f such fabric are punched therefrom in the operation of the machine. The disks of card board or other material are either received in a hopper or reservoir or are stamped out directly in the present machine. In the operations of feeding the various parts, the assembling thereo-f, and the discharging of the finished button backs, the machine is completely automatic. The machine is particularly de signed for turning out a. large amount of work; the various moving parts are light so that their inertia or momentum will not be a serious factor and the various movements are made easy, the cams having gradual inclines, etc. so that there is nothing to prevent the machine operating at eX- ceedingly high speeds.

' In order that my invention may be fully understood, I will now` proceed to describe an embodiment thereof, having reference to the accompanying drawings illustrating the same, and will then point out the novel features in claims.

In the drawings: Figure 1 is a top view of the machine with certain parts broken away to show other parts beneath them. Fig. 2 is a view in side elevation of the machine. Fig. 3 is a front view thereof. Fig. 4 is a View in vertical transverse section through the machine, the plane of section being taken substantially upon the line 4-4 of Fig. l. Fig. 5 is a A'transverse sectional view of the. machine substantially upon the plane of the line 5 5 of Fig. l. Fig. 6 is a detail top view of certain parts of t-he step by step feeding mechanism for the turn tables. Fig. 7 is a view of the machine in horizontal section upon the plane of the line 7 7 of Fig. 2. Fig. 7a is a detail view in transverse vertical section upon the plane of the line 6& 6a of Fig. 7 Fig. S is a detail sectional View through the cloth cutting mechanism, the plane o-f section being taken substantially upon the line 8--8 of Fig. l. Fig. 9 is a detail sectional view upon the line 9-9 of Fig. I, showing the parts in condition for the cloth washer to be pressed into the collet. Fig. l0 is a detail sectional view upon the plane of the line lO-lO of Fig. l showing a follower disk as held in position over a collet, and a. plunger in position above the same. Fig. l1 is a detail sectional view upon the plane of the line 11-11 of Fig. 6 showing the completed button back as it appears when being ejected. Fig. l2 is a detail view in perspective showing a section of the cloth strip, a cloth washer removed therefrom, and a collet beneath the same. Fig. 13 is a view in perspective showing the cloth washer as having been received within the collet, and showing a follower disk in a position above the same ready to be received within the collet. Fig. 14; is a view in perspective looking upon the finished butto-n back from above. Fig. l5 is a view in perspective of the finished-button back looking from below. Fig. 16 is a detail View in side elevation of `a modified form of the apparatus in which the follower disks are stamped out ot strip material instead ot' being supplied 'from a hopper. Fig. 17 is a sectional view upon the plane of the line 17-17 of Fig. 1G. Fig: 18 is a sectional view upon the plane ot the line 18-18 of Fig. 16.

llet'errinpl first to the machine illustrated in Figs. l. to 11 inclusive7 2O designates a trame work, the upper portion ot which supports a drive shaft 21. The drive shaft ,is provided with a suitable helt wheel 22 with which itI may be driven, and with a miter gear wheel 233, the teeth of which are in mesh with the teeth ot a complementary miter lgear wheel 24. mounted tast upon a vertical shatt 25. Att its lower end, the vertical shatt 25 is provided with another miter Lgear 26, the teeth ot which are in mesh with the teeth ot a miter gear 27 disposed upon a shaft 28, the axis ot which is arranged at right angles to the axis of the drive shaft 2l. The said sliat't 28 is provided at its opposite end with another miter Igear wheel 29,theteeth ot which are engaged in mesh with the teeth ot a complementary @gear 30 seclu'ed tast to a horizontal sha'tt 31, the anis ot which is arranged at right angles to the axis oit the shat't` and parallel with the axis ot the shatt 21. The three shaft-s 2l, 2S and 31 together with the connecting shatt 23 constitute the means by which the various parts ot' the machine are driven. rlhe toi-ward end oli the main shaft 21 is provided with a crank pin or eccentric 32, the same being mounted in a hearing` block SB which is in turn mounted and arranged to slide in a guideway 341 in a plate the latter being` arranged to reciprocate vertically in a suitable guideway 3G secured to or termed a part ot the trame of the machine. Secured tast to the plate is a head 3T in which are mounted a plurality ot plungers. Rotation ot the drive shaft 21 transmits a vertical reciprocating movement through the crank pin or eccentric 32 and the hearing` block to the plate 35 and hence to the head 37 and the plungers carried thereby. lil'ounted immediately beneath the head 3T and the plungers carried thereby is a turn table 38. The said turn table is mounted tast upon a central shaft 39 (see particularly Figs. 4l and G) to which shaft is also secured a, ratchet wheel 40. 'ihe turn table 3S rests in a rabbeted portion ot the bed plate ot the machine trame, the tace ot the turn talole being preferably substantially flush with the tace ot the said bedv pl ate. rlhe shaft of the said turn tahle rotatably mounted in a hub 42 which is secured to the trame work by means ot arms T3, oris formed as a part thereof. Step by step movements ot' rotation are imparted to the turn table 38 through the medium of the ratchet wheel by means ot' suitable connections with the vertically reciprocating head 37. These connections include a hell crank lever pivoted at l--lupon an arm l5 which uprises trom the bed plate ot the machine, one arm t6 ot the said bell crank lever beiufe` arranged to engage a yoke t7 and the other arm 48 of which is connected to a slide t9 (see Fig. 5). rllhe slide 419 is provided with a pawl 50 (see Fig'. 6) which is spring` pressed in ay direction to engage the teeth of the ratchet wheel 40. By reference to the drawings it will readily he seen hat the vertical reciprocatingl movements oit the head 37 are converted hy the bell crank lever into horizontal reciprocating' movements ot the slide 49, such horizontal reciprocating` movements being; adapted to impart intermittent step by step movements to the ratchet wheel l() and hence to the turn table 38. lt will, moreover, he seen that the ratchet wheel is actually moved during` the return or upward movement ot the head, the downward portion ot the movement ot' the head representing; the idle or return portion ot the movement of the slide 49 or that portion of its movement when the pawl t8 is withdrawn from a` tooth of the ratchet wheel for 'the purpose oit causing;` it to enwith another toot-h. The lengthwise movement ot the slide is somewhat greater than is necessary to move the pawl a distance between two teeth ot the ratchet wheel whereby there is a. certain amount oit lost motion or overthrow, this lost motion being :tor a purpose to be present-ly explained.

1n addition to the turn table 3S, there is another turn table 51 in the machine l am now describing, (see particularly lFigs. il and (i). rll`his turn table is moun'ed above the level of the turn table 38, and a portion thereoie overlaps a portion ot' the said turn Vtable SS. rlhe said turn table. 5l mounted upon a. central spindle 52, the said spindle bein#v rotatably mounted in the hed plate ot the machine, and beingl also permitted to have a limited vertical or longitudinal movementI therein. N ear its lower end, the spindle 52 is provided with a t'eed ratchet the said ratchet wheel being); splined to the spindle 52 so that while the two parts will positively rotate together, a limited relative vertical movement is permitted. t its lower end, the said spindle 52 is received within a housing 54, a spring 55 heing provided for forcing` the spindle and the table carried thereby normally to an upward position. Step by step movements o t' rotation are imparted to the ratchet wheel simultaneously with the movements imparted to the table 38 by means oli' a spring` actuated pawl 56 which is mounted upon an arm 57, one end ot which is loosely disposed around the stem 52, and the other end of which has a slotted connection with a pin 58 carried by the slide ett). l.lllhen the slide 49 is reciprocated, the arm 56 is given an angular movement about the ratchet wheel 58 and the pawl 57 is thereby caused to carry the ratchet wheel with it. when moving in one direction to pick up a fresh tooth when moving in the opposite direction.

The cross shaft 28 is provided with a cam 59 which engages a cam follower 60 upon a vertical link 61, the upper end of which is pivotally connected with hoppers (S2-68. rlhe hoppers or reservoirs 62 and 68 are in turn pivotally supported at 64 upon standards 65 which uprise from the base plate of the machine. The shaft 28, in its rotation, will impart vertical reciprocating movements to the link 61 and tilting or tipping movements to the reservoirs or hoppers' 62, 68 about their support 64. The reservoir 62 is arranged in communication with a chute 66 which leads to a point near the periphery of the turn table 51, while the hopper or reservoir 68 is arranged in communication with a chtite 67 which leads to a feeding device 68 in proximity to the periphery of the turn table 88- at the side opposite to that at which the turn table 51 is located. The feeding device for the collets comprises a slide 69 which is disposed' in a guideway 70, a rocking arm for imparting reciprocatory movements to the slide, and a link 72 which connects the upper end of the arm 71 with the slide 69, the lower end of the said arm 71 being pivotally mounted at 78 to a bracket 74k secured to, or formed a part of, the fra-me of the machine. A cam 75 mounted upon theshaft 81 engages a follower 76 upon the arm 71 to impart rocking movements thereto. At its outer end, the said shaft 81 is provided with a disk 77 which carries a crank pin 78 radially adjustable thereon. The said crank pin 78 is connected by means of a link 79 with an operating arm 80 which is loosely mounted upon a spindle 81 of a feed roll 82. The feed roll 82 is one of a pair of feed rolls which are arranged to feed a strip of fabric from a roll 88 across the upper surface of one portion of the -.turn table 88. Mounted fast to the spindle of the feed roll 82 is a ratchet wheel 84, the teeth of the said ratchet wheel being arranged to be engaged by a. pawl 85 upon the arm 80. Movements of rotation of the shaft 81 effect reciprocatory movements of the feed rolls 80 through the connections aforesaid whereby to impartthe step by step feeding movements to the strip of fabric from the noll 88.

rlhe operation of the machine is as follows: First the reservoirs or hoppers 62 and 68 are charged respectively, the hopper 62 with disks 86 of card board or similar material such as are shown in the upper portion of Fig. 18, and the hopper 68 with collets 87, similar to that shown in the lower portion of the Fig. 12. In first charging the machines it will of course, also be neces sary to fill up the chutes 66 and 67. A roll of fabric will also be mounted in the machine as shown in 88 in Fig. 1, the end of the fabric being passed between the feed rolls 82. The machine being now started up, the active portion of the cam 75 will give a quick rocking movement to the arm 71 whereby the slide 69 will be caused to feed one of the collets 87 which has been presented thereto from the chute 67 to a point in the turn table immediately below a plunger 88 of the head 87, and immediately above a die 89 in the turn table 88. The parts are so timed that just as the collet is brought to the proper' position, the plunger 88 will descend and force it into the die 89. The plunger will then retreat as the head 87 moves upward, and it being remembered that a step by step movement is imparted to the turn table 88 during the upward movement of the head 87, such movement of the turn table will now take place, the turn table being moved one-eighth of a revolution, in the construction shown in the drawings. At each eighth of a revolution, the turn table comes to rest and a fresh collet is fed fo-rward by the slide 72 and is forced into the next succeeding die in the turn table by means of the plunger 88, it being understood that the turn table 88 is provided with eight dies 89 equidistantly arranged around the same. When the turn table has moved through one quarter of a revolution, the die containing the cup which was inserted by the plunger 88 as above described is brought opposite a plunger 90. The face of this plunger is made in the form of a cutting die or punch and it is arranged, in its descent, to cut out a disk or washer 91 from the fabric strip 92, and to force it into the re` ceiving portion of the die in the turn table so that it will lie above the collet contained therein as is shown in Fig. 9. At the next eighth of a revolution of the turn table 88, the die containing the washer and collet is brought beneath a plunger 98, the diameter of which, near the lower end thereof, is substantially equal to the interior diameter of the collets 87, and which is provided, at its extremity, with a projection 94 which is arranged to pass through an opening 95 in the collets 87.

lhen the collet and washer are in the position shown in Fig. 9, immediately beneath the plunger 98, and the head 87 is moved downward, the plunger 98 will force the washer into the collet and the central portion of the washer through the opening therein so that the washer will be caused to lie in the position and form in which it shown in Figs. 10, 18 and 1-5. At the next step by step movement, the turn table will have completed one-half of a revolution and the die carrying the collet with the cloth washer contained therein will be immediately beneath the turn table 51. r1`he turn table 51 has a plurality of pockets 90 in which are arranged tub-es, the ends t-hereof being split to form spring lingers 97. The card board disks which are fed from the hopper or reservoir 02 down the chtite G6 are d-elivered into a recess 98 in the bed plate of the machine just beneath one of the pockets 00 in the turn table 51. The head 37 carries a plunger 00 which is located immediately above the top of the spindle 52 of the turn table 51 so that at each reciprocation of the head. 33T, the turn table 51 is depressed by the action of the said plunger 99 against the resistance of the spring 55. This causes the spring fingers to embrace the disk in the recess 01 and to pick up the same, and as a similar movement occurs after each step by step movement of the turn table 51, (the turn table 51 being actuated, it will be remembered, at the same time the turn table 38 is actuated), the pockets of the said turn table 51 will be loaded in succession. The plunger 90 is arranged in a housing 100 secured fast to the head 37 or made as a part thereof, a strong spring 101 being contained in the housing and operating to press the plunger downward into its operating position. The spring 101 is stronger than the spring 55 so that the spring 55 will be depressed by the action of the plunger, but the spring 101 will take care of ,any overthrow or excess movementof the head 3?'.

From the foregoing, it will be understood that the pocket 05 in the turn table 51, which is in line with the die 80 of the turn table 38 in the last mentioned position, (namely diametrically opposite to the feeding device G8), will contain a card board disk, and that such card board disk will be held immediately above the mouth above the die S0 as is shown in Fig. 10. rllhe head 3T carries a plunger 102 which is disposed imn'iediately above this point, so that as the head descends, the plunger 102 will enter the pocket 00 to engage the upper face of the said card board disk; in the continued downward movement of the head, the plunger 90 will engage the end of the spindle as aforesaid so that near the completion of the downward movement of the head 37, the turn table 51 will be carried downward to cause the fingers 97 to enter the mouth of the die S9. At the extremity of the said downward movement, the plunger 102 will force the card board disk into the collet in the die S9 so as to complete the formation of a button back. 1t is during this final movement that the spring 101 of the plunger 99 is depressed.

rlhe button back having now been completed, it only remains to eject the same. rllhis is accomplished by means of a stationary cam 103 (see Fig. 11). r1`he dies 89 are formed with relatively stationary cheek" piece 101 and relatively movable head 105, the latter being carried by stems 106. lThe stems 100 are provided with head 10i' at the lower end thereof, springs 10S being disposed between the head 107 and the lower surfaces of the turn table 38. P1`he heads 105 rest snugly in pockets 109 in the turn table, the springs holding them firmly therein until the heads 10i1 are engaged by the stationary cam 103. rithey are so engaged during a step by step movement of the turn table, the result being to life the button back to ay point with its lower face about the level of the top of the turn table. 1n th-e continued rotary movement of the turn table, these button backs are received by a discharge chute 110 along which they are gradually forced by the movement of the turn table to be finally delivered at any suitable point.

1t will be understood that while 1 have described the production of a single button back in the cycle of operation of the machine, it is nevertheless true that a complete button back is delivered at each reciprocation of the head 37. The various steps above described are carri-ed on simultaneously upon successive elements at the various points, a new collet being inserted in a die at the first position of the table, a fresh washer being inserted at the third position, the washer being forced home and the central portion being forced to protrude in the fourth position, and the card board disk being forced into place in the fifth position, all at the same time. The delivery takes place, as has been before stated, during the step by step movement of the turn table while the head is retreating after the plungers have operated. lt will also be understood that the turn tabl-e 51 is moved downward to receive the card board disk at one point therein at the same time as a card board disk is being' discharged therefrom at another point into a die in the turn table 3S.

1n order to insure the correct positioning of the turn tables 38 and 51, l have provided the head 37 with two spring pressed plungers 111, 112, the former being adapted to engage one of a set of recesses 113 with which the turn tabl-e 38 is provided, and the other to engage one of a set of recesses 111 with which the turn table 51 is provided. rEhe ends of these plungers are preferably tapered and the recesses 113 and 114 in the turn tables are correspondingly tapered so that the position of the tables may be corrected within small limits by the action upon them of the plungers 111, 112. lThere is, of course, one recess for each position of each table. The tilting movements which are given to the reservoirs 02 and 63 by the cam 59 during the operation above set forth have the effect of continuously supplying the chutes (S6 and 67 with disks and collets respectively as they are discharged at the lower ends thereof, so as to form a continuous feed therefor. The upper end of the chutes 66 and 67 are preferably flared as appears in Figs. 1` 3 and 5 of the drawings so as to present a wide opening to receive the articles.

In Figs. 16, 17 and 18, I have shown a construction which I may employ when I desire to punch out the card board disks directly in the machine instead of feeding them from the hopper or reservoir 62; in such a case I provide a magazine 115 for containing blank strips of car board or other material of which the disks are to be composed, and I provide feeding means therefor for feeding the blanks forward. and punching means for punching the disks from the blanks. The feeding means may conveniently comprise a feeding' roller 116. the said feeding` roller being provided with a ratchet wheel 117, a spring pressed pawl 118 which is adapted to engage the teeth of t-he ratchet wheel, a rocking lever 119 which carries the said pawl, an operating arm 120. the upper end of which is connected by a link 121 with the rocking` lever 119. and the lower end of which is pivoted at 122 to a stationary support, and a crank pin 123 radially adjustable upon a disk 124 secured to a driving shaft 125. The driving shaft 125 is provided with a miter gear wheel 126, the teeth of which will be arranged to mesh with the miter gear 26 upon the vertical shaft 25 of the machine. The feeding means just described feeds the blank strip of card board or other material over a table 127 which takes the place of a turn table 51. The table 127 is provided with the female portion 128 of a die. the male portion being comprised in the plunger 102. IVhen the plunger 102 descends` it will cut out a blank disk out of the card board strip and will push it through a passage 129 in the table 127. An arm 13() carried bv a spring pressed spindle 181 is supported beneath the table 127. the said arm being provided with a pocket 132 immediately in line with the passage 129. The said pocket is formed in a tube, the ends of which are split to form spring fingers 97 exactly similar to the spring fingers carried by the turn table 51. Vhen the head 37 descends, the said plunger 99 will engage the spindle 131, depressing the arm 130 in the same manner as the turn table 51 was depressed in the example of my invention shown in the other figures so as to cause the springfingers 97 to present the card board disk directly to the die 89 beneath the same. It is, of course, understood that when the foregoing mechanism is used, the arm 13() and spindle 181 are employed in place of the turn table 51 and the spindle 52, and furthermore that the feed pawl 56 for the turn table 51 is removed, disconnected or otherwise rendered inoperative.
